ICE-MACHINE;

SPECIFICATION forming part of Letters Patent No. 344,310, ed n 1886- I Application filed August 20, 1885. Serial No. 174,591. (No umuei.)

principle that when a liquid is changed to a state of vapor,or a gas is expanded, the result is. the abstraction of heat from neighboring bodies or substances.

The object of myinvention is, primarily, to construct an apparatus for the manufacture of ice and for refrigerating purposes that shall be of small cost, portable, and automatically and easily perated.'

The invention consists in such construction and arrangement of tanks and of the coils for conducting the vaporizing or expanding gas that said gas may be used for both the freezing orrel'rigerating operation andfor cooling the recondensed gas. 'It might be added that this portion of "my invention is generally applicable tothis class 01: ice-machines.

The invention further consists in arranging the condenser or pump in the tank for cooling the recondensed gas, forfthe purpose hereinafter fully explained.

In the accompanying drawings, in the several fignresof which like parts are similarly designated, Figure l is a side elevation of an apparatus embodying my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a perspective ,view with parts broken away and I the comlenser-operating mechanism removed.

Fig. at is a perspective view of a vessel for receiving a liquid or substance to be frozen or cooled. Fig. 5 is a sectional view on the line a: m of Fig. 6. Fig. 6 is a top plan view of the apparatus with the operating mechanism for the condenser removed, and Fig. 7 is a 10ngitudinal section of the condenser.

- The letter Adesignates the freezing or refrigerating tank, and B the tank in which the recondensed gas is cooled or condensed. These tanks are, preferablyformed by dividing a single vessel into two compartments by a partition secured liquid-tight therein.

chines for the manufacture of ice in which the.

.0 representsthe receiver or tank for the liquid ammonia or gas-evolving agent. This receiver or tank 0 communicates through a suitable pipe, 0, with a series of coils, D, the 5 flow into said coils being regulated by a suitablc cock, 0". The expanding or vaporizing gas circulates through these coils D and absorbs heat from any substance insaid tank, as usual in this kind of apparatus. These coils communicate with another coil or series of coils, E, in the recondensed-gas-cooling tank 13. The gas, after passing through these coils and cooling the water contained in said, tank, enters at the inlet into the condenser 01'' pump F. This condenser F by compression recondenses the gas to a fluid form, which thereby becomes heated and evolves heat. The liquid thus heated is passed through the outlet of the condenser into the coils E, which are cooled by thev water,which in turn was cooled by the passage of the gas through the coils E in the tank B. The recondensed gas passes thence back to its primary receptacle 0, when the process is repeated.

The evolution of heat from the condensed in the condenser heats said condenser, I therefore submerge said condenser in the cool ing-tank. It is obvious, however, that the condenser might be otherwise cooled.

As shown in Figs. 1 and 2, the tank is fitted with a frame, a, having a top cross piece or beam, 1), and also intermediate cross-pieces, 0. Upon cross-pieces c are mounted in suitable bearings the shafts d and d. The shaft (2 has 8 fitted at one end'a large geanwheel, c, and a pinion, c,and the shaft (1" has a pinion, '0 engaging the pinion 0'. At the ends of the pieces or. beams c, or at the sides of the frame a, are

mounted upon suitable shafts a large chaingear, f, and a small chain-gear or pinion, f, the shaft of the pinion f being provided with a crank for imparting a reciprocating" motion to the piston-rod of the condenser or pump F- Chain g connects the gear e and pinion it upon the shaft of the gear f, and a similar chain,

'9, connects the gear f and the pinion f.

Cords or bands i are fastened to and wound around theshaftscl d, as drums, and passover pulleys k, journaled in the cross piece b. The ends of the cords are provided with suitable weights, Z, which tend to turn theshafts d and d, to impart the necessary motion. A suitable means for winding the cords upon the shafts may be provided.

I would state here that the means just particularly described for operating the condenser-piston may obviously be changedor modified, or a spring motor, instead of a weight, used for driving the moving parts.

As shown in Fig. 7, the condenser cylinder F is fitted with suitable heads, forming a compression-chamber, F. The bottom head, or the bottom of the cylinder itself, is of sufficient thickness to contain the valves. The inlet and outlet top head is fitted with stuffingboX and glands necessary to pack the pistonrod that passes through the same. The gasis introduced from the coil E into this compressing-chamber through alarger opening, m, fitted with an inlet valve, m, and is discharged through a smaller opening, a, fitted with an outlet-valve, a, into the coils E in the condensing-chamber. The inlet-opening is made larger than the outlet, in order that a downward movement of the piston will receive the resistance necessary for compressing the gas. v

It is evident that the vessel showuin Fig. 4 may be of any other shape or construction desired. l

\Vhat I claim is 1. The herein-described apparatus for the manufacture of ice, or for refrigerating purposes, comprising a vessel or tankfor containing a vapor or other gas-evolving agent, a refrigerating or freezing tank having suitable circulating coils connected with said gasevolving tank, and a separate tank for containing water cooled by a coil or coils communicating with the coils in'the freezing or refrigerating tank, and a condenser having its valved inlet connected with sald water cooling coils, and having its valved outlet con nected with the cooled coils in said tank,which latter returns the condensed gas to its primary -eirculating-coils connected with said gasevolving tank, and a separate tank for containing water cooled by a coil or colls communicating with the coils in the freezing or refrigerating tank, and a condenser submerged in the cooled liquid, and having its valved in let connected with said water-cooling coils and having its valved outlet connected with the cooled coils in said tank, which latter returns the condensed gas to its primary receiver, as

set forth. V

3. The combination, with the primary gasproducing-agent receptacle, the freezing or refrigerating tank, and the recondensed-gascooling tank separate from said freeZingtank, and the condenser in the circuit, of the pipes and coils in said tanks, and means, substantially as described, for producing a forced circulation of the gas.

In testimony whereof I have hereunto set my hand this 13th day of August, A. D. 1885.

Correction in Letters Patent No. 344,310.

It is hereby certified that in Letters Patent No. 344,310, granted June 22, 1886, upon the application of Abner Evans, jr., of Philadelphia, Pennsylvania, for an improvement in Ice Machines, an error appears in the printed specification requiring correc tion, as follows: In line 14, page 2, the words inlet and outlet should be stricken out, and the same inserted before the word valves in line 13, same page; and that the Letters Patent should be read with this correction therein that the same may conform to the record of the case in the Patent Office.

Signed, counter-signed, and settled this 29th day of June, A. D. 1886.
